tutorial-annotated-concept-checker

tutorial-annotated-concept-checker is an agent for Claude Code from wahidyankf/ose-public. It costs 54 tokens per session (751 once invoked), scanned A, original, MIT.

A tutorial review agent that checks one annotated-concept lesson's mode, worked examples, and diagrams against its quality rules. It reports rated findings without modifying the lesson.

In plain words
What is it for?
It helps review whether examples explain the concept, include the required context and takeaways, run as shown when they contain code, and meet density rules.
Why use it?
It catches inconsistencies in examples and explanations while keeping product-specific thresholds in the adopting repository rather than inventing its own.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tutorial-annotated-concept-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Tutorial Annotated Concept Checker

The tutorial-annotated-concept family's checker. It judges one annotated-concept tutorial for the Tutorial Annotated Concept Quality Gate and reports. It changes nothing.

Normal Workload

It reads the subject once, from the gate's own rules, since the catalog publishes no skill for this kind, and rates each breach. Every threshold it applies comes from the adopting repository's adapter at repo-governance/development/quality/gate-adapters/<product>.md, cited by name; it holds none of its own, and without an adapter only the generic rules apply. Validating against fixed criteria is execution work.

What It Checks

The gate's cycle owns the questions; this checker answers them:

  1. Mode first: the tutorial's declared mode holds, and a no-code tutorial containing a code block is a CRITICAL finding. Every later question branches on the mode.
  2. Each worked example carries context saying why the concept matters, a fitting medium, a key takeaway, and any part the adapter adds; a code-bearing example runs as printed, and in no-code mode each decision artifact spells out its reasoning.
  3. Density: comment lines divided by code lines per code-bearing example fall within the adapter's band.
  4. Across the tutorial, worked examples cluster by theme and rise from simple to real-world, a diagram appears only where a visual relationship materially aids understanding, and the count meets the adapter's floor for the mode.

Medium fit, clustering, progression, and decision-artifact quality are judgement rows. Prose, facts, and links belong to Content Checker, and properties in the gate's Deterministic Boundary are never findings.

Findings

Each finding names the file and worked example, the rule or adapter threshold it breaks, what was observed, a measured value where the rule is a band or floor, and a criticality from Criticality Levels. It returns findings to the gate, which records them in its ledger. Confidence is rated later by Tutorial Annotated Concept Fixer.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tutorial-annotated-concept-checker is an agent published in the GitHub repository wahidyankf/ose-public (12 stars, last pushed today), licensed MIT. It adds 54 tokens to every session and 751 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-14.
